postqueue -fgeneralmente se usa para vaciar la cola, después de que se resuelve la causa raíz del error de entrega.
-f Flush the queue: attempt to deliver all queued mail.
This option implements the traditional "sendmail -q" command, by
contacting the Postfix qmgr(8) daemon.
Warning: flushing undeliverable mail frequently will result in
poor delivery performance of all other mail.
postqueue -ise puede utilizar para un mensaje específico:
-i queue_id
Schedule immediate delivery of deferred mail with the specified
queue ID.
This option implements the traditional sendmail -qI command, by
contacting the flush(8) server.
This feature is available with Postfix version 2.4 and later.
Si tiene una interrupción permanente de IPv6, puede desactivar IPv6 en postfix con inet_protocols.
Dehttp://www.postfix.org/IPV6_README.html:
/etc/postfix/main.cf:
# You must stop/start Postfix after changing this parameter.
inet_protocols = ipv4 (DEFAULT: enable IPv4 only)
inet_protocols = all (enable IPv4, and IPv6 if supported)
inet_protocols = ipv4, ipv6 (enable both IPv4 and IPv6)
inet_protocols = ipv6 (enable IPv6 only)
